This invention relates to' continuously attached envelopes and hasparticular reference to afseries vof envelopes which vare connectedtogether-fin strip formation to permit yoffthe,convenientfeeding of thestrip through a'typewriter or' addressegraph for addressing theenvelopes.v

An object of the yinvention, is to provide a series of continuouslyattached envelopes in'which adjacent envelopes are integrally connectedtogether by narrow tabs located adjacent the opposite ends I thereof andwhich narrow tabs `may be readily severed for separating the envelopes.Another object of the invention isto Vprovide a series of continuouslyattached envelopes in which the front and rear walls of 'each'envelopeare integrally connected together at one end of the envelope and inwhich one of the said w-alls is formed with side flaps adhesivelyjoining the front and rear walls together at the opposite side edgesthereof. -f f" Still another vide a series of continuously attachedenvelopes which are so" constructed fand arranged thatthe same may beeconomically produced from `a single sheet or length of paperwithoutlwaste'in forming the envelopes. Y r; f-, Y. y

I Still another object of vide two connected series of continuouslyattached envelopes arranged side by'side parallel'frelation `with theenvelopes in one series connected with the envelopes inthe'other seriesby weakened lines topermit of the' convenient separation thereof afterthe envelopes are addressed. 4

With the foregoing and other objects in view, reference is now made tothe following specification and accompanying drawings in which thepreferred embodiments of the invention are illustrated. f Y

the invention is to profrom which a series of continuously" attached' YFig. 8 isa fragmentary sectional view ftaken approximately online4ir---ii ofFig. 61. ,e l Referring tothe drawings by characters ofreference, the 'envelopesflll in continuously attached formation yareproduced from van elongated strip of paper which is of any desired widthand of continuous formationtoprovide any desired depth and width ofenvelope and any desired number thereof in' attached formation.`A Theen-` velopeslil are 'Iso constructed and arranged that ai single seriesor two series ofcontinuously atetached envelopes may be produced from asingle strip of paper. The envelopes in a single series 'or in connectedseries are adapted to be disposed in stacked formation `for continuouslyfeeding the same through atypewriter or addressograph for addressinglthe envelopes. 'y y In Figs.` 1 to VVl inclusivel of the drawings, astrip'of paper II is illustrated which is 'provided with' lines-'adaptedto show the` mannerin which a f'sing'le' series of envelopes I 0 areproduced therefrom infacc'oifdance with the invention. The strip `vvI IAis cutaway in-rectangular'formationas at I2 at longitudinalequallyspaced locations forming oppositely disposed transverselyextending edges I3 and Ill,` At theopposite ends of the cut vawayportions I2 Vnarrow tabsr I5 vand I6 are'pro'vided which-formconnections joining adjacent envelopes lill -The7narrow tabsv Iearelocated along a lOngitudinally--extending line I1 while the narrowjtabsI6`arelocated along the side edge I8. Between the longitudinallyextending linei'l and a longitudinally"extending line i9 the strip 'is'transversely slit at longitudinal kequally 4vspaced 4edges of the frontwall 2B of each of the envelopes from which two connected series ofcontinuously are'folded into underlying relation with the rear wall 21thereof and `adhesively secured thereto to form a pocket between thefront and rear walls. The tabs .I5 may be lprovided 'with' weakened or,zperforatedlines 28rand'29 While the tabs IS'inay be provided withweakened or perforated lines'iac and3l topermit of convenient tearing ofthe tabs onsaid lines to separate' the envelopes from'series .formationlafter the envelopesfhave lbeen addressed.

The strip I I is also cut away as at 32 at longitudinal spaced locationsbetween the side flaps 22 and 23 and the side edge 33. This forms theclosure flaps 34 which are folded on the longitudinally extending lineI9 into overlying relation with the rear wall 21 for adhesively sealingthe envelopes in closed relation.

In Figs. 5 to 8 inclusive of the drawings, a strip of paper 65 isillustrated which is provided with lines adapted to show the manner inwhich two series of continuously attached envelopes I are producedtherefrom in accordance with the invention. The strip 35 is divided intoparallel portions 36 and 31 by a longitudinally extending line 36located medially betweenv :the opposite side edges 39 and 40 of theAstrip. Portions 36 and 31 of the strip are cut away in a rectangularformation as at 4I and 42 respectively at longitudinally spacedlocations to form oppositely vdisposed transversely extending edges 43and 44 extending inwardly from .the `side edges 39 ,and 40 of the stripportions .36 and 31 to narrow tabs 45 and 446 located along thelongitudinally .extending lines 41 and 48 respectively. AThelongitudinallyextendingline 41 is located medial- 1y between the sideedge 39 Aandna longitudinally extending line 49 of the strip portion 36,while the line 4 8 is disposed medially between the side edge 40 .and alongitudinally vextending line 50 of the strip portion`31. The narrowtabs =45 .and 46 provide connections xjoining adjacent envelopes I IIformed from the portions 36 `and 31 of the Strip. Narrow tabs `5I arealso provided which are located in lateral .alignment with the tabs :45and 46 and disposed between the longitudinally extending lines 4 9 and50.

The strip is transversely slit at longitudinally spaced locations as at6 2 .between Vthe longitudinally extending lin 4] and 40 and as at 53between the longitudinally vextending lines 48 and 0 so as Ato formoppositely disposed rectangular shaped .naps 54 and i5 in the-stripportion 3 6 and oppositely disposed rectangular shaped side flaps 56 and51 .in the :strip `portion 31 which are `folded on the transversely.extending lines 58 and 6.9 located 'in alignment with .theVtransversely .extending edge portions 43 and 44.

The .strip portion `3 6 is folded on the .longitudinally extending line41 to provide the vfront walls 60 ofthe envelopes and the rear walls 6Ithereof which latter walls are disposed in-overlying relation with thefront walls. The side flaps 64 and 53 at the opposite edges of the frontwalls 60 are folded into underlying relation with the rear walls 6I andadhesively secured thereto so as to form Apockets rbetween said walls..The strip portion 31 .is Similarly folded on the longitudix-iallyuextending line 46 so .as to Aform the front walls 62 of the envelopesand the rear walls 63 thereof, which `latter walls are disposed inoverlying vrelation with the front walls and have the side flaps 58 and59 folded under :the rear walls and adhesively secured thereto .to Vformthe `pockets between the .front and rear walls of the-envelopes. Thetabs 45 .and 4 6 maybe provided with weakened or perforated lines 64 and65 connecting Yadjacent `envelopes. and the tabs-5I may be provided withweakened o rperforatod lines 56 andi! 'which .form the .ends oftheclosure flaps 68 and 69 of the twoseries respectively when the envelopesare separated- The closure flaps 68 are folded on the' fold line Y48`while `the closure flaps 6 9 are folded on the longitudinally extendingYline 50 and adhesively secured to therear walls of the envelopes in theseries respectively for sealing the same.

This provides two series of envelopes in which the series are connectedtogether by the weakened or perforated longitudinally extending line 10joining the flaps 68 and 69 and in which the envelopes in each seriesare connected together by narrow tabs which permit of the folding of theconnected strips in stacked formation for continuously feeding the twoseries through a typewriter or addressograph so that lthe envelopesdisposed inside by side relation in the series may be addressed and thenext succeeding envelopes `in each series moved into position in thetypewriter or add-reograph for addressing the same.

The rear walls 21 of the envelopes I0 in the -formfshown .in Figs. l to4 inclusive of the drawings .are somewhatnarrower than the front walls26. This disposes the weakened lines 28 and 29 anni!) and 3| inwardly ofthe side edges 24 and 25 of the front wall so that when the tabs I5 andJ6 .are ysevered along said weakened lines, the frayed edges areinwardly of the side edges of the envelope. In this jormalso the stripis slit along the longitudinally vextending lines I1 and I9 to form theendsl of .theilaps 22 and 23.
